Vinorelbine and prednisone in frail elderly patients with intermediate-high grade non-Hodgkin's lymphomas.

BACKGROUND: Frail patients with non-Hodgkin's lymphoma (NHL) are generally excluded from clinical trials and not even treated. The aim of this study was to evaluate the efficacy and tolerability of vinorelbine and prednisone in frail elderly patients with NHL. PATIENTS AND METHODS: Thirty consecutive frail elderly patients were entered in a phase II study with vinorelbine 25 mg/m2 i.v. on days 1 and 8 and oral prednisone 30 mg total dose on days 1-8 for six cycles. Criteria of frailty were age > or =80 years, or age > or =70 years and three or more comorbidities of grade 3 or at least one comorbidity of grade 4 according to the Cumulative Illness Rating Scale (CIRS), or not self-sufficient or the presence of one or more geriatric syndromes. RESULTS: Of 30 evaluable patients, three (10.0%) achieved a complete response (CR), nine (30.0%) showed a partial response (PR), while 10 presented with stable disease and eight with progressive disease. The median duration of CR was 29 months (range 5-36 months), and the median duration of PR was 1 month (range 1-22 months). Three patients had grade 3 neutropenia and one had grade 4. One grade 4 neurotoxicity was observed. Three patients died because of heart failure within 28 days of therapy, and one patient died after 4 days because of rapid progression. The median overall survival was only 10 months. CONCLUSION: Vinorelbine and prednisone is a relatively non-toxic combination with modest activity in frail patients with NHL. If initial aggressive chemotherapy has been excluded, this combination could be tried to obtain a temporary palliation.

Cemp, a mitoxantrone containing combination, in the treatment of intermediate and high grade non-hodgkin's lymphoma: an effective and non toxic therapeutic alternative for adult and elderly patients.

Here we report the results of a randomised multicenter phase III clinical trial which assesses the therapeutic efficacy and tolerability of a chemotherapy protocol CEMP (cyclophosphamide, etoposide, mitoxantrone and prednisone) in adult and elderly patients with advanced intermediate and high-grade NHL. Between October 1991 and October 1995, 139 patients, aged 55 to 79 years, with diffuse intermediate and high-grade lymphoma, were enrolled. A considerable percentage of patients had clinically aggressive disease: 32.4% had systemic symptoms, 79% had stage III or IV disease, 33.8% had bone marrow involvement, 46% had splenic involvement and 42.5% had increased values of serum lactate dehydrogenate. Complete remission was achieved in 70 of the 139 patients (51.9%) and PR in 12 (16.6%) with an overall response of 68.5%. The overall response survival rate at 6 years was 39%, whereas DFS rate was 48.7% and PFS rate was 28.5%. At four years 49% of the patients were still in CR. Dividing the patients in two groups, under and over 65 years of age, we obtained the same results as far as overall response is concerned. No toxic deaths occurred, neither cardiac, renal nor liver complications happened. CEMP regimen is an effective and safe protocol with good results in elderly people, well comparable to those achieved in younger ones.

Elderly ovarian cancer: treatment with mitoxantrone-carboplatin.

OBJECTIVE: Data concerning optimal treatment of elderly patients with ovarian cancer are scanty. The management of ovarian cancer in the aged patient is many-sided: the diagnosis can be difficult and delayed, and aggressive surgery is often not attempted because of concomitant morbidity. We tested a combination of carboplatin and mitoxantrone potentially associated with low toxicity in elderly patients with ovarian cancer. METHODS: Eighty-two patients older than 70 years (median age, 75; range, 70-88) with epithelial ovarian cancer were referred to our multicenter group and enrolled into this pilot study. Carboplatin (JM8) was given at the dose of 230 mg/m2 and mitoxantrone at the dose of 9 mg/m2 every 28 days. RESULTS: Dose-limiting toxicity was represented by 4 cases of thrombocytopenia and 1 case of gastrointestinal toxicity. These 5 episodes occurred in 328 assessable cycles, representing a low toxicity profile (3%). Of the 68 assessable patients, 36 (53%) did not respond to chemotherapy (no change + progressive disease), complete response was observed in 15 (22%), and partial remission was observed in 16 (23.5%), accounting for an overall response rate of 45%. CONCLUSION: The carboplatin-mitoxantrone combination, at the dosage tested in this study, appears to be well tolerated by elderly patients with advanced ovarian cancer and is associated with an acceptable response rate. Optimally debulked patients also showed improved survival when compared with patients with more extensive tumor.

VACOP-B, high-dose cyclophosphamide and high-dose therapy with peripheral blood progenitor cell rescue for aggressive non-Hodgkin's lymphoma with bone marrow involvement: a study by the non-Hodgkin's Lymphoma Co-operative Study Group.

BACKGROUND AND OBJECTIVE: Sequential treatment with the addition of high-dose therapy (HDT) and peripheral blood progenitor cell (PBPC) rescue has been reported to be active as front-line therapy in aggressive non-Hodgkin's lymphoma (NHL) with bone marrow (BM) involvement. We designed an intensive sequential therapy as front-line therapy in this subset of patients and conducted a phase II study. DESIGN AND METHODS: Patients with aggressive non-Hodgkin's lymphoma and BM involvement at diagnosis received 8 weeks of VACOP-B chemotherapy as induction therapy. The second phase included high-dose cyclophosphamide (HDCY) (7 g/m(2)) with granulocyte colony-stimulating factor (G-CSF) followed by leukaphereses. The third phase included HDT according to the BEAM protocol or melphalan (140 mg/m(2)) plus total body irradiation (8 Gy in a single dose). RESULTS: Forty patients were included in the study. According to the intention-to-treat, after VACOP-B, 11 (27.5%) and 22 (55%) patients achieved complete remission (CR) and partial remission (PR), respectively. Thirty-four received HDCY. After HDCY, 18 patients (45%) were in CR and 13 (32.5%) in PR. Twenty-nine underwent HDT plus peripheral blood cell rescue (PBPC) rescue. At the completion of treatment 29 patients (72.5%) were in CR, and 3 patients (7.5%) in PR. The actuarial 3-year overall survival, disease free survival and failure free survival are 48%, 55% and 40%, respectively. Overall severe toxicity was 7.5%. INTERPRETATION AND CONCLUSIONS: This phase II study suggests that the intensified treatment described is feasible and active in aggressive NHL with BM involvement. A randomized trial is now underway to test this approach.

Gastric MALT lymphomas: the value of an endoscopic follow-up evaluation.

BACKGROUND: Findings have demonstrated the close association between primary gastric B-cell lymphomas originating from mucosa-associated lymphoid tissue (MALT) and Helicobacter pylori (HP) infection, with their regression after an HP eradication therapy in up to 70% of the cases. Endoscopic-biopsy diagnosis and endoscopic ultrasound are of major importance as decisive prognostic factors and therapeutic determinants. OBJECTIVES: We report 3 years of experience and follow-up evaluation in the management of MALT lymphomas. We also describe the guidelines strategy therapy used in our institution. METHODS: Since July 1996, nine patients with a histologic diagnosis of low-grade, HP-positive MALT gastric lymphomas, have been followed up. All patients had stage IE lymphomas (according to Musshoff classification). Eradication of HP was performed with triple therapy amoxycillin, clarithromycin, and omeprazole using over a 14-day period. The patients were seen for endoscopic follow-up assessment after 3, 6, 9, and 15 months, then twice a year. The actual median follow-up time was 30.4 months (range, 16-38 months). RESULTS: All the patients are now free of disease and asymptomatic. We have registered two cases of HP relapse (both after 1-year follow-up evaluation), positively treated with the same triple therapy, and three cases of disease relapse treated with single-dose chemotherapy (plus radiotherapy in one patient). CONCLUSIONS: In our experience the eradication of HP appears to be effective, and we consider it the first therapeutic option in patients with stage IE gastric low-grade MALT lymphoma, although long-term results are still needed. Prolonged follow-up evaluation (particularly by endoscopy) is necessary (and feasible in our experience) to determine whether these remissions are long-lasting. We recommend that HP be eradicated in these lymphomas before referral to other standard treatment.

Gastric non-Hodgkin's lymphoma: analysis of 252 patients from a multicenter study.

AIMS AND BACKGROUND: The stomach is the most common site of primary extranodal non-Hodgkin's lymphoma (NHL) and no agreement has been reached so far on the best therapeutic approach. The main objects of this study were to report the long-term results and to evaluate the importance of some possible prognostic factors in a large series of patients. NHL was considered primary gastric if the main symptoms at presentation were those of gastric disease. METHODS AND STUDY DESIGN: We analyzed 252 consecutive patients treated between 1980 and 1993 in five hospitals in north-east Italy. According to the Working Formulation, 98 patients had low grade lymphoma, 59 intermediate grade (D to F), 81 G or high grade and 14 were not classified. The patients were divided into two groups: one including patients with limited disease (localized to the stomach or perigastric lymph nodes: 165 patients) and one including those with advanced disease (87 patients). The treatment consisted of surgery, chemotherapy, radiotherapy or combinations of these. Sixteen patients received only supportive therapy. RESULTS: The five-year overall survival was 65.4%: 80.3% for patients with limited disease and 36.7% for those with advanced disease (P < 0.0001). Among the limited disease patients the five-year survival was 84.4% for those treated with gastrectomy alone and 88.7% for those who received also adjuvant chemotherapy (P = 0.11). However, while chemotherapy did not improve survival in low grade NHL, it seemed to produce a better survival in the intermediate and high grade groups (P = 0.06). Twelve patients were treated with primary chemotherapy and the five-year survival was 71.2%. In multivariate regression analysis the most important variable for overall survival was surgery for the whole group of 252 patients (P < 0.0001), while it was age for the group with limited disease (P = 0.0008). CONCLUSIONS: Surgery alone can be curative for most patients with gastric lymphoma limited to the stomach or to the perigastric lymph nodes; surgery followed by chemotherapy seems to produce better results than surgery alone in intermediate and high grade lymphomas. Also a non-surgical approach with first-line chemotherapy is associated with a high rate of complete remissions and five-year survival. In advanced disease the five-year survival is similar to that of nodal NHL.

Chemo-immunotherapy of advanced AIDS-related Kaposi's sarcoma.

AIMS AND BACKGROUND: Kaposi's sarcoma (KS) is the most common neoplastic complication of HIV infection and AIDS. Multiple cytotoxic chemotherapy regimens have been used with various response rates. We have evaluated the efficacy and toxicity of low-dose chemotherapy in patients with poor-prognosis AIDS-related KS and the role of interferon alpha (IFN-alpha) in complete responders. METHODS: Twenty-five previously untreated patients with advanced KS received bleomycin (BL) 10 mg/m2 and vinblastine (VB) 6 mg/m2 on days 1 and 15 every two weeks. After six cycles, patients in complete remission received IFN-alpha (3 million U s.c. 3 times/week) combined with antiretroviral therapy. All patients were evaluated for toxicity using the World Health Organization (WHO) toxicity schedule. Both Eastern Cooperative Oncology Group (ECOG) and AIDS Clinical Trials Group (ACTG) response criteria were used to evaluate response and survival. RESULTS: The overall response rate was 84% (95% confidence interval, 51-117%) with six complete remissions (24%) and 15 partial remissions (60%) by ECOG criteria, and 92% (95% confidence interval: 58-128%) with 17 partial remissions (68%) by ACTG criteria. The median duration of response on IFN-alpha treatment was 4.5 months (range, 2-10). The overall median survival duration for all 25 patients was 9 months (range 2-39). Grade 3-4 anemia was observed in five patients and grade 3-4 neutropenia in two patients. No other clinically significant (> or = grade 3) toxicities were observed. CONCLUSIONS: Combination of BL and VB is effective and well tolerated, even if new therapeutic options are developing. This disease remains a challenging problem, so larger studies using the combination of chemotherapy and/or IFN-alpha with antiretroviral treatment are warranted.

VACOP-B versus VACOP-B plus autologous bone marrow transplantation for advanced diffuse non-Hodgkin's lymphoma: results of a prospective randomized trial by the non-Hodgkin's Lymphoma Cooperative Study Group.

PURPOSE: The aim of this multicenter randomized study was to compare conventional therapy with conventional plus high-dose therapy (HDT) and autologous bone marrow transplantation (ABMT) as front-line treatment for poor-prognosis non-Hodgkin's lymphoma (NHL). PATIENTS AND METHODS: Between October 1991 and June 1995, 124 patients, aged 15 to 60 years, with diffuse intermediate- to high-grade NHL (Working Formulation criteria), stages II bulky (> or = 10 cm), III, or IV were enrolled. Sixty-one patients were randomized to receive etoposide, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin (VACOP-B) for 12 weeks and cisplatin, cytarabine, and dexamethasone (DHAP) as a salvage regimen (arm A), and 63 to receive VACOP-B for 12 weeks plus HDT and ABMT (Arm B). RESULTS: There was no significant difference in terms of complete remissions (CRS) in the two groups: 75% in arm A, and 73% in arm B. The median follow-up observation time was 42 months. The 6-year survival probability was 65% in both arms. There was no difference in disease-free survival (DFS) or progression-free survival (PFS) between the two groups. DFS was 60% and 80% (P = .1) and PFS was 48% and 60% (P = .4) for arms A and B, respectively. Procedure feasibility was the major problem. In arm B, 29% of enrolled patients did not undergo HDT and ABMT. A statistical improvement in terms of DFS (P = .008) and a favorable trend in terms of PFS (P = .08) for intermediate-/high- plus high-risk group patients assigned to HDT and ABMT was observed. CONCLUSION: In this study, conventional chemotherapy followed by HDT and ABMT as front-line therapy seems no more successful than conventional treatment in terms of overall results. However, our results suggest that controlled studies of HDT plus ABMT should be proposed for higher risk patients.

Surgical second look in ovarian cancer: a randomized study in patients with laparoscopic complete remission--a Northeastern Oncology Cooperative Group-Ovarian Cancer Cooperative Group Study.

PURPOSE: The usefulness of extensive and repetitive surgery for patients with ovarian cancer still remains unproven (at least for some conditions). We planned an accurate prospective test of the hypothesis that patients with advanced-stage disease, after they had reached a clinical complete remission (CR), may benefit from surgical second look (SSL). PATIENTS AND METHODS: One hundred two patients in CR (as assessed by clinical findings, markers, and visualization by computed tomographic [CT] scan and laparoscopy), after initial debulking and first-line chemotherapy, were randomized to two arms, which were well balanced for predictive criteria such as age, stage at presentation, histology, grading, date of randomization, and residua after first surgery. Forty-eight patients were randomly assigned to receive follow-up evaluation only, while 54 were assigned to receive second surgery (eight of them refused). Of 46 surgical patients, 35 had negative and 11 positive surgical findings (24% clinically false-negative). RESULTS: Despite the microscopic residua found at open surgery, and the fact that the patients were then treated with second-line chemotherapy, SSL did not increase the probability of survival in this setting. In an analysis of the results according to the intention-to-treat criteria, after a 60-month follow-up period, the overall survival rates in the two groups of patients (SSL v no SSL) were 65% and 78%, respectively (P = .14). Multivariate analysis according to predictive criteria confirmed there was no significant difference between the two groups (P = .39). CONCLUSION: Our study shows the following: (1) our second-line treatment is scarcely effective; (2) SSL accurately defines complete responders to first-line chemotherapy; (3) SSL per se does not prolong survival; and (4) if confirmed, a less invasive procedure could replace SSL as a valuable method in new first-line regimens in ovarian cancer patients with clinical CR confirmed by laparoscopy.

Hybrid MOPP/ABVD and radiotherapy in advanced Hodgkin's disease.

BACKGROUND: In patients with advanced Hodgkin's disease (HD), the alternation of MOPP with ABVD or hybrid MOPP/ABVD are associated with a high CR rate and a high probability of 5-year survival. However, even after effective chemotherapy the risk of nodal relapse is not negligible, and not only in initial bulky site(s) of disease. For this reason, in an attempt to prevent relapses after combination chemotherapy alone, we performed a prospective study to evaluate the efficacy and toxic effects of 6 courses of hybrid MOPP/ABVD followed by radiotherapy (RT) in stages II A bulky, II B, III and also in stage IV with bulky disease of residual after chemotherapy. PATIENTS AND METHODS: From January 1985 to August 1993, 133 patients with HD (128 newly diagnosed, stage II A bulky-IV, 5 in first relapse after RT) were treated according to the following program: 6 courses of the hybrid MOPP/ABVD regimen followed by RT (STNI + spleen in stages II A, II B, III without pelvic lymph node involvement, TNI + spleen in stage III with pelvic lymph node involvement, involved field in stage IV with bulky disease or residual after chemotherapy). The total dose of RT was 4000 cGy to the sites of bulky or residual disease and 2000 cGy to the other sites. RESULTS: After hybrid MOPP/ABVD, 107 of 130 (82.3%) fully evaluable patients were classified as in CR or CR(U). After completion of RT, 108 patients were in CR and 3 were in PR, for an overall response rate of 85%. With a median follow-up duration of 45 months, the actuarial 5-year survival is 76% and the progression-free survival 68.6%. So far, only 14 patients have relapsed (6 within the irradiation field) and the 5-year relapse-free survival is 82.5%. CONCLUSION: Six courses of hybrid MOPP/ABVD followed by RT in stages II A bulky, II B, III and in stage IV with bulky disease or residual after chemotherapy produced a high CR rate with low risk of relapse. However, a longer follow-up is necessary to evaluate the late effects of combined therapy.

Prolonged survival (17 years) in a patient with chronic myelogenous leukemia after therapy for Hodgkin's disease.

A case of secondary chronic myelogenous leukemia after successful therapy for Hodgkin's disease is reported. The patient was diagnosed as having stage IIIA Hodgkin's disease, at the age of 33. He underwent staging laparosplenectomy and was treated with radiotherapy plus chemotherapy. Forty three months after the diagnosis of Hodgkin's disease, a Philadelphia-positive chronic myelogenous leukemia developed. It required periodic chemotherapy and each time a remission, lasting several months (up to 14 months), was obtained. The disease had an unusually prolonged clinical course, and the blast crisis, of lymphoid type, occurred only 17 years later.

MACOP-B versus ProMACE-MOPP in the treatment of advanced diffuse non-Hodgkin's lymphoma: results of a prospective randomized trial by the non-Hodgkin's Lymphoma Cooperative Study Group.

PURPOSE: The aim of our study was to compare in a multicentric randomized trial two regimens widely used in the treatment of advanced-stage intermediate- to high-grade non-Hodgkin's lymphoma and to assess whether a third-generation regimen (methotrexate with leucovorin, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin [MACOP-B]) was superior to a second-generation regimen (procarbazine, methotrexate with leucovorin, doxorubicin, cyclophosphamide, and etoposide [ProMACE-MOPP]). PATIENTS AND METHODS: Between January 1987 and August 1991, 221 patients with diffuse intermediate- to high-grade non-Hodgkin's lymphoma (Working Formulation groups F, G, H, and K), stage II bulky (> 10 cm), III, or IV, were randomized by the Non-Hodgkin's Lymphoma Cooperative Study Group (NHLCSG) to receive ProMACE-MOPP for six cycles or MACOP-B for 12 weeks. Survival, progression-free survival, and disease-free survival were determined, and multivariate analysis of prognostic factors was performed. RESULTS: In the two groups of patients, there was no significant difference in terms of complete remission (CR) rate (49.1% with ProMACE-MOPP and 52.3% with MACOP-B), 3-year overall survival rate (45.2% with PROMACE-MOPP and 52.3% with MACOP-B), and 3-year progression-free survival rate (36.4% with ProMACE-MOPP and 36.1% with MACOP-B). In terms of toxicity, no significantly greater toxicity occurred in either arm. Overall toxicity was acceptable. The most frequent side effects were grade II through IV leukopenia, infection, mucositis, and anemia. Treatment-related deaths were equally distributed. CONCLUSION: No significant differences in terms of efficacy and/or toxicity between ProMACE-MOPP and MACOP-B are evident. These results are consistent with recent randomized trials showing that the new-generation aggressive regimens are no better than previous ones.

Late relapses in Hodgkin's disease: outcome of patients relapsing more than twelve months after primary chemotherapy.

BACKGROUND: Patients with Hodgkin's disease whose initial complete remissions (CR) after primary chemotherapy were longer than 1 year are thought to have better prognoses than patients whose initial remissions were shorter than 1 year. However, only a few studies have analyzed the long-term survival in addition to the results of retreatment in patients relapsing after CR lasting more than 1 year. PATIENTS AND METHODS: We analyzed the data of 40 patients with Hodgkin's disease who were treated in a single institution and whose CR were > 1 year after primary chemotherapy. Therapy at relapse was not standardized: of 36 patients evaluable for response, 29 received second-line chemotherapy and 7 received radiotherapy alone. RESULTS: Sixty-five percent of the patients obtained CR (median duration: 21 months). Sixty-eight percent of the complete responders relapsed again; however, long-lasting third and fourth remissions were observed. All of the 7 patients whose retreatment consisted of radiotherapy alone obtained CR, but only 1 is in continuous CR. The presence of nodular sclerosing histologic subtype, the absence of extranodal involvement and the use of hybrid MOPP/ABVD or ABVD alone as salvage treatment are independently associated with a higher CR rate and a higher probability of 5-year survival. The 5-year survival for all 40 patients is 49%. For the patients obtaining CR, the 5-year survival and the 5-year relapse-free survival are 76% and 25%, respectively. However, the survival curve continues to fall in the succeeding years because of third and fourth relapses and the occurrence of secondary acute leukemia and non-Hodgkin's lymphoma. CONCLUSIONS: A high percentage of patients relapsing more than 12 months after primary chemotherapy can obtain second CR. Even if most of our patients eventually relapse, third and fourth CRs are not uncommon. However, the long-term survival is low and it is further diminished by secondary leukemia and non-Hodgkin's lymphoma.
